Application filed May 12, L904. Serial No. 207.595.

To all whom it .may concern.-

Be it known that I, COLOM-AN DE KANDQ, a subject of the King of Hungary, residingat Budapest, in the Kingdom of Hungary, have invented certain new and useful Improvements inElectric Cars and Locomotives, of

"motor is driving the .wheels by means of cranks and connecting rods, the bearings of the motor are subjected to strains which produce premature wearing of the brasses, so that it soon becomes necessary. to adjust them. In the case of electric mo tors, the airgap of which scarcely amounts. to one or two millimeters, the adjustmentof bearings is a very complicated matter, and it is very difficult to keep the fixed and the rotating parts in exactly concentric position. v

My invention has, among other things, for its object to. provide means whereby it is made possible to adjustthe bearings which receive the crank-pressure without the relative position of the stationary and rotating 'partsof the motor being affected.

My invention consists of certain novel parts combinations of parts particularly pointed out in the claims concluding, this specification.

. The invention will be more readily understood by'reference to the accompanying drawings, forming a part of this specification, in which-i e Figure 1 is a longitudinal section of the motor? and its bearings; Fig. 2, a. side elevation showing the yielding suspension of the stationary part, a part of the car-frame, and

. of the connecting-rodi Fig. 3 is a diagrammatical perspective YiW of combined motor armature and crank-bearing, a part of the former being broken away. I

Referring in detail to the drawings, 1 is the stationary part or stator of the motor. 10 is the casingof the same. 2 arethe bearings secured to the motorcasing or formed integral with the same.

Mounted within the casing is the rotating part or armature 3 the shaft 30 of which is journaled in the bearings 2 securing the with relationto the field structure.

exact. concentric position of the armature Owing to the yielding'suspension of the casing in the manner described hereinafter, the bearings 2 cannot take up the crank-pressure and only have to support the .wright of the shaft .30

and of the'armature 3,'so that owingto, this small load these hearings wearvery little and 'do not require adjustment.

The casing 10, containing thie stationary part of the motor, is-suspended by means. of

links 8, connected, respectively, by pivots ll and 12 to the casing and to the framewbrkor The links 8, which support zontal movement to the united stationary and rotating part of the motor. 7

f The shaft 30 is provided with ill the pins 13 of whichare journaledin bearings of (Shown only partly in the drawings.) The connecting-.-

rods 14; are driving two or more car-wheels drawings.) v

The crank-pressure (indicated by arrows p) is taken up by a' separate bearing 4, which is mounted in the vehicleframe 7, so that the (Not shown in the;

latter forms an abutmentagainst 'Which the bearings can be made suitably adjustable without reference to the concentric relative positions of the stationary part and the arforces produced by the crank-act." These mature, for whenthe bearing 4 is adjusted and the position of the shaft alteredthe latter moves the stationary part 1 by means of the bearings 2, so that the relative positions always remain the same. =The bearings 2' can also be combined as shown in Fig. 3. "j

Another form of bearings involving my inventiom-i's shown in Fig. 3. 5 is a sleeve or hearing carried-by the frame of the motor corresponding to the bearing 2 of Fig.1. In thisbearing the shaft 30 of the motor is journaled, as has already been described. This bearing is cut away on opposite'sides in line with the direction of the strains produced by the crank-shaft. Through said out-away portions blocks or brasses 6 6 are inserted,

the inner ends of these brasses being curved to eonicrm to the interior contour of the sleevegr bearing 5. The shaft 30, journaled in said sleeve 5, is therefore in contact with and is held between the inner ends of these blocks 6 6, which inner ends form portions of for said shaft. The locks 6 6 bear against the -journal-bearin outer ends of the abutments on the oar-frame, to which abutments the strains produced by the crankshaft are transmitted. The blocks 6 6 therefore perform .thevfunctions of the bearing. 4 of Fig. 2, these blocks being made adjustable' to compensate for wear. It will therefore be seen that the bearing 5 for the shaft 30 isfree to move in the direction. of the.

strains produced by the crank-shaft, while the bearings 6 6 for said shaft are rigid in the" direction of the strains produced by the crankshaft.

It should be noted that the invention can be applied as well on cars as on locomotives.

The present disclosure presents only one embodiment of my invention, and I there fore do not wish my invention to be unduly .limited, since its features can be varied indirection of the driving strains, and bearings for the rotating part unyielding in the direction of the driving strains.

L 2. In an electric vehicle, the combination ofa frame, a motor, a crank-shaft driven by said motor, bearings for su porting said n o'- tor said bearings being yie ding in the direc .tion of the strains produced by the crankshaft and bearings rigid in the direction of strains produced by the crank-shaft 3. In an electric vehicle, the combination of a frame, a motor, suspension-rods for supporting said motor pivotally connectedto the frame and the motor, a crank-shaft driven by said motor and a bearing rigid in the direction of the strains produced by the crank-shaft.

of a frame, a motor, the rotatingelement of which is journaled in bearings carried by the stationary element, flexible means for supporting said motor, a crank-shaft driven by the rotating element, and a bearing in the vehicle-frame for receiving driving thrusts communicated through the crankshaft.

6. In an electric vehicle the combination of a frame, a motor, means for sup orting said motor, a crank shaft driven y the rotating element of said motor and an in-.

dependent bearing for receiving driving thrusts communicated through the crankshaft.

7. In an electric vehicle the" combination of a motor having concentric stationary and rotating'elements, bearings for maintaining the concentric relation of said elements, means for supporting said motor yieldingly in the direction of the driving pressures, and bearings; transmitting such driving ressures to the vehicle independently of the stationary part of the motor. t
